Carbs , calories what the hell works ?

Calories always matter--count them with a digital food scale, and try to stay within your calorie goal everyday. Consistency wins. Move more and MFP will give you more calories to eat. Low carb, paleo, keto, all ways of eating, but not necessary unless you have specific health problems. Eat what you like--just less. Good luck.

Calories do matter when you are doing low carb. Some people naturally eat fewer calories on low carb, so they maintain or lose without having to count. Sometimes this happens because it's a significant diet change, you cut out the foods you used to overeat, and it takes a while to come up with new things to overeat. Sometimes it happens because you find yourself satiated on less with low carb.

I had a similar thing happen when I was doing a 100% plant based diet for Lent one year. I didn't intend to lose, but I lost quite a bit, probably because I hadn't yet figured out what the high cal things I could overeat were, heh. I suspect that if I had stayed with that diet I'd have figured it out and found a way to maintain or gain, as with any other diet.

Low carb can be beneficial to some even if they still have to count calories or watch them somewhat because they find it easier to hit their calorie goal. Lately I find lowering carbs makes me less likely to overeat, which hasn't always been my experience (and I'm not especially low carb, more like 100 g).

Calories do matter with low-carb. If you are constipated you either need to up your fat intake or magnesium. There are other things to eat than halloumi, aaannnd 6 biscuits wouldn't derail you.

Sounds like you were looking for the 'quick fix' mis-guided people have been hearing about. *eye-roll*

No matter what you call it, or how you are losing the weight, it is ALWAYS a result of eating less calories than your body is burning. ALWAYS.
How you arrive there may have many different names, but to get there, you are eating less calories than you burn.

Did low carb many times and the only reason it worked for me is I got sick of protein and fat so ended up eating less. The initial weight loss is water. Low Cal works and is sustainable over a long period of time where low carb for me was impossible to maintain. If you had a big loss at the beginning of your low carb you will gain that back in the beginning of low cal so don't get discouraged. In time the water balance in your body will normalize and you will begin to lose fat.

No real need for low carb just start at like 30 to 40 carbs and work up to where u start to put weight back on then take 10 grams off a week until u start to lose weight - got to have carbs for energy more so if u run n do cardio too
